The absolute worst deck to use is the Latios / Latias starter set, known as Eon Strike.
Oh dear lord.
The only good cards are Latios / Latias, but they need Psychic energies up the wazoo. And semi-decent trainers. But no - you get Acro bikes. And that's it.
I can''t even beat the gold trainers on one start challenge.
And the other basics all require copious amounts of energy cards, and I'm really upset.
Anyone have any luck with this deck, or other starter decks? (Granted, the Latis were okay for being Psychic pokemon for the versus challenges involving them until I got Gengar-EX, but the rest of it is pitiful.)
Anyone have any other horrid decks they'd like to share, or recommend against getting?
